SQL Server and Oracle too but not being open source is a big minus.
I mean, its a lot more expensive than Postgres for very very little benefit. Like what exactly is the value proposition? Is it saving developer time? faster? I guess none of those
These days a I am not so sure what the case would be other than legacy or very occasionally some feature only SQL Server has. AD would be a big one.
Today I have no idea about SQL server but if the support is as good today as it was back then it can be worth it.
